Parts for your 2020 Mazda Bt-50-Steering bushes

2020 Mazda BT-50 steering bushes — purpose, wear, and service advice

Steering bushes are fitted to the 2020 Mazda BT-50. The BT-50 (UP/UR series) runs a rack-and-pinion steering gear mounted to the front crossmember using rubber insulator bushes. This is shown in Mazda’s workshop manual and parts catalogue for the UP/UR BT-50, which list the steering gear mounting bushings as serviceable items, and is backed up by major aftermarket catalogues (for example, SuperPro lists a steering rack mounting bush kit specifically for 2012–2020 BT-50). Routine service schedules for the BT-50 in Australia and New Zealand also call for periodic inspection of the steering system and related bushes.

On this ute, the steering bushes isolate the rack from the chassis, soaking up vibration while keeping the rack securely located. Good bushes mean tidy on-centre feel, quiet operation and consistent toe control over corrugations and big hits. When they’re tired, the rack can shift slightly under load, which shows up as vague or notchy steering, a clunk on turn-in or over potholes, and sometimes a tendency to tramline. Left too long, that movement can speed up inner tie rod and tyre wear.

There isn’t a fixed replacement interval for BT-50 steering bushes, condition depends on use. Vehicles that tow, run heavy accessories, or see regular gravel and off-road work usually age bushes faster. A visual check at each service is smart: look for cracked or oil-soaked rubber and any witness marks that suggest the rack has been moving. A quick road test can confirm—feel for a dull knock through the column or a delayed response as you take up steering.

• Replacement tips: use quality OE-equivalent rubber for factory feel, or reputable polyurethane if the vehicle carries extra weight or spends time off-road and the owner prefers crisper response.
• Best practice: torque mount hardware at normal ride height, and follow workshop procedures to avoid rack or line damage.
• After-fitment: book a wheel alignment check. Toe can change slightly when the rack position is restored.
• Preventative care: keep engine oil and power steering fluid leaks off the bushes, as petroleum can degrade rubber.

Done properly, fresh steering bushes bring the BT-50 back to feeling planted and predictable, which is exactly what most Aussie and Kiwi owners want from their daily workhorse and weekender.

Popular questions about 2020 Mazda BT-50 steering bushes

What are the signs the BT-50’s steering rack bushes need replacing?
Common signs include a faint clunk when turning at low speed or hitting potholes, vague on-centre feel, and slight steering wander or tramlining. A workshop inspection may show cracked or compressed bushes, or witness marks around the rack mounts where it’s been shifting under load.

Should the BT-50 use rubber or polyurethane steering bushes?
For most daily-driven utes, quality rubber gives the most factory-like comfort and noise control. Polyurethane can sharpen steering feel and lasts well in tough conditions, making sense for touring, towing or off-road setups. If noise, vibration and harshness are a priority, stick with rubber, if precision and durability matter more, consider poly from a trusted brand.

Do I need a wheel alignment after replacing steering bushes?
It’s wise to check alignment. Restoring the rack to its correct position can nudge toe settings. A quick alignment ensures even tyre wear and that the BT-50 tracks straight.
